To all whom, it Hwy concern.-

Be itknown that I, Eennnr I-I. Gone, a citizen of the United States, residing at Chicago,.in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Engines, of which the following is a specification.

My invention relates to improvements in engines suitable for various uses, although shown for convenience as arranged inconnection with a fluid-circulating systemf An object of my invention is to provide a rotary engine which may be operated with a minimum expenditure of steam or of like motor fluid, which may be operated by a steamcurrent which is used to supply a heating system in which there maybe but a slight difference in pressure between the feed and exhaust sides of the engine, and to afford a mechanism in which the engine may be readily driven by a slight motor force and in such a manner that the engine will carry no load in its initial operation and will automatically unload whenever its speed becomes less than that required to carry the load. These and other objects are attained by my invention, whiclsis more specifically set forth in the accmnpanying claims and.

which is shown in one convenient embodiment thereof in the accompanying drawings, in which- Figure 1 is a sectional view through the engine mechanism and accompanying parts arranged for a circulating system. Fig. 2 is a sectional Yl(\ on the line 2 2 of Fig. 1 looking in the direction indicated by the arrows. Fig. 3 is a like view on the line 3 3 of Fig. 1. 4 is a like view on the line 1 4 of Fig. 1. 5 is a like View on the line 5 5 of Fig. 1. 6 is a like view on the line 6 6 of Fig. 1. Fig. 7 is an enlarged sectional detail of a part of the engine mechanism. Fig. 8 is a sectional viewon the line 5 8 of Fig. 7 looking in the direction indicated by the arrows, and Fig. 9 is a detail of one end of one of the motorarms.

Like numerals of reference indicate the same parts in the several figures of the drawings.

As shown in the accompanying drawings, 1 indicates a supply-pipe for a suitable mo tor fluid, such as steam under pressure, through which steam flows into a chamber in the box 2, which is provided on one side of the motor-casing 3. Extending axially through the box 2 is the shaft 4, journaled within the walls of the box 2 and extending outwardly through a stufiing-box 5. This shaft 1 also extends into and across the motor-casing 3 and is shown as journaled at 6 in said casing. The shaft 4 has preferably some longitudinal play and is provided with a collar or flange 7. The inner end of the box 2 is closed by a cap 8, through which the shaft at extends and within which it may be journaled, if desired. Loosely mounted on the shaft 4 and between the flange 7 and cap 8 is a packing-ring 9 of Jenkins material or any other kind of suitable material. The shaft 4 is hollow on the interior of the box 2 to the end which is journaled at 6, andult is provided with a perforation or passage 10, connecting the interior of theshaft with the interior of the box 2.

Mounted upon the shaft 4 within the motor-casing 3 are two sets of motor-arms 11 and 12, which are hollow, connecting the interior of the shaft 1 and which are provided with constricted openings at their outer ends, through which they discharge into the interior of the casing 3. The shaft 1 is prefer ably provided with an enlarged chamber '13, with which the motor-arms 11 and 12 "are connected. Mounted upon the shaft 4: is a fly-wheel 15. The motor arms 11 are bent I to discharge toward the angle formed by the wall 16 with the wall 17 of the casing 3, in or across which angle are arranged a plurality of corrugations or pockets 18, the wider faces of which extend in such a plane that the jets discharged from the bent ends of the motorarms 11 will strike vertically against said faces and so as to force the shaft 4 toward the bearing 6, as well as to rotate the shaft 4. The discharge ends of the motor-arms 12 are also bent, but are preferably bent in the plane of rotation of the arms 12 and so as to impinge against a plurality of pockets 19, provided on the interior of the casing 3, the shorter walls of which pockets are substantial radially to said casing and are connected by long inclined or curved walls, which connect the base of one short wall with the apex of the next, so that the jets projected from the motor-arms 12 will impinge inost directly against the short radial walls thus exerting the highest efficiency in rotating the shaft 1. As a result of this construction the force exerted by the jets projected from the arms 11 and the pressure of steam within the box 2 against the flange 7 will tend to force the shaft 4 toward the bearing 6 and to compress the packing washer or ring 9 hey tween the flange 7 and the cap 8, thereby suiiiciently packing the oint between the in terror of the box 2 and the interior of the casin 3.

Stearn entering the box 2 through the pipe 1 will have no outlet, except through the opening 10 into the interior of the shaft 2 and thence into the chamber 13. These passages are preferably so roportioned that in its initial flow steam wiil enter the chamber 13 much more rapidly than it will flow out through the arms 11 and 12,, so that a body of steam under pressure will gather within the chamber 13, As the pressure within the chamber 13 increases the velocity of the flow through the arms 1]. 12 will correspon'dingly increase until the inflow through usual manner in steadying the operation of the mechanismand in tending to'contin'ue the rotation of the shaft 4. I

. Keyed to the outer end of the shaft 4 be yond the stuffing-box 5 is a disk 20, to which are pivoted clutch-arms. 21. These clutcharms 21 are held in their normal position, as shown more clearly in Fig. 5, by springs 22,

and are provided at" their outer ends with weights 23. v

Stops 24 serve, in conjunction with the springs 22, to hold said arms in v their position of rest. These clutch-arms, it

' will be noted, arev in the shape of a bell-crank lever, the long arm of which in a position. of rest extends tangentially to the disk 20.

Journaled within the propeller-casing 24 is a shaft 25, supported at .one end by a bracket 26 and j ournaled' at the other end in said casing and extending through a stuffing-box 27. Said shaft is also provided with a collar 28, which serves as a stop to limit the movement of saidsh aft in the direction of the motor-casing'3. The free ends of the shaft 2 and the shaft 25 are arranged closely adjacent to each other, and the free end of the f'eshaft 25v has keyed to it a disk 29, which is rovided with an annular flange 30, extendmg toward the disk 20 and around a lateral pro ection 31 on the short arms of the clutcheyers 21, said projections 31. being provided with a friction face adapted to make frictlonal. contact with the inner face of said flange 30.

Mounted upon the shaft 25 within the projailer-casing 24 are propeller-blades 32, set

at such an angle that the normal operation ceases of the device the rotation of the blades 32 willvforce water out of the casing 24 through the pipe 33. As steam enters through the pipe 1., the box 2, and shaft4 it is projected through the arms 11 12 into the interior of the motor-casing 3, whence it finds a free outlet through the pipe 34 and is conducted to the water-jacket 35, surrounding the motor- 1 casing 24, which operates as a condenser, the

water of condensation being automaticall discharged in any suitable manner throng the pipe 36. As the rotation of the shaft 4,

caused by the projection of steam through the motor-arms 11 12, increases in rapidity the centrifugal weights 23 on the clutch-arms 21 are thrown outwardly against the tension of the springs 22 and the lateral projections are brought into frictional contact with the inner face of the flange 30 on the disk 29. As this frictional contact is established it starts the rotation of the disk 29 until the disks 29 and 20 are rotating in unison, with a corresponding rotation of the shaft 25 and the pr0- peller-blades 32. peller-blades 32, as before explained, forces water out of the propeller-chamber 24 through the pipe 33 and draws water into the This rotation of the pro propeller-chamber 24 through thepipe 3.7.

It will thus be seen that with the described embodiment of my invention in its initial operation the motor carries no load, except the friction incident to its own operation, and

acquires no load until it has ac uired a speed which brings the friction-clutc tion, such operation of the friction-clutc being to gradually put the load on the motor until the apparatus is running at full speed. It will also be noted that the high s eed of retation acquired by the fly-wheel efore the friction-clutch is in operation tends to continue the rotation of the motor as the load is gradually put on it by the o eration of the clutch device; but whenever, )ecause of failure of the motive forceor for any other reason, the motor slows down' the springs 22 will overcome the centrifugal action of the weights 23, the clutch willbe disconnected, and the engine unloaded, whereupon it may operate freely and without load until it ac-' quires sufficient velocity to again operate the clutch mechanism connecting it with its load.

into 0 era- I I have illustrated an arrangement in which the steannpipe 34 leads from the motorcasing 3 to a jacket 35, which surrounds the propeller-casing 24, from which jacket the pipe 36 leads to any convenient point." In this arrangement the jacket 35 and casing 24 constitute a convenient form of condenser, which is conveniently arranged immediately adjacent to the motor-casing 3, so as to quickly produce. an operative dlfi'erence in pressure between the inlet-pipe and the exhaust-pipe- 34 of the engine, while at the same time utilizing the exhaust of the engine to heat the water of a circulating system. Nevertheand arranged adjacent to the discharge end rior of said casing, at different angles but so less I contemplate any useto which my en- 'ine may be put for carrying any kind of a l oad and do not limit myself to an apparatus in which the exhaust from the engine is utilized for any purpose Whatever. Neither do I limit myself to the use of steam as a motor fluid. So, also, while many variations in details may occur to those skilled in the art as a matter of convenience, shop expediency, or mechanical skill all such changes are within the contemplation of my invention and regardless of whether or not the load is carried directly by the engine or by means of a clutch connection or otherwise.
